"Definition of Done" (DoD) and the "Definition of Ready"

 In Agile methodologies like Scrum, the "Definition of Done" (DoD) and the "Definition of Ready" (DoR) are two important concepts used to ensure that work is well-defined and meets certain criteria before it is started and completed within a sprint or iteration.

Definition of Ready (DoR) sets the criteria for backlog items to be considered ready to start work, while the Definition of Done (DoD) sets the criteria for work items to be considered completed within a sprint. These definitions help Agile teams maintain transparency, quality, and consistency in their work processes. They are essential tools for effective Agile development and ensure that everyone on the team understands what needs to be accomplished at each stage of the development cycle.


1. Definition of Ready (DoR):

  • The Definition of Ready is a set of criteria that user stories or backlog items must meet before they are considered ready to be worked on in a sprint or iteration.
  • It defines the prerequisites that need to be satisfied for a task or user story to be eligible for selection in a sprint backlog.
  • Criteria in the DoR might include clear acceptance criteria, detailed requirements, and any necessary design work.
  • The DoR helps the team ensure that they are not starting work on items that are unclear or insufficiently prepared, reducing the risk of scope changes or misunderstandings during the sprint.


2. Definition of Done (DoD):

  • The Definition of Done is a set of criteria that must be met for a user story or task to be considered completed and potentially shippable.
  • It defines the quality and completeness standards that a product increment must adhere to before it is considered done.
  • The DoD typically includes criteria such as passing all acceptance tests, code reviews, documentation updates, and potentially integration or deployment to a staging environment.
  • The DoD ensures that work items are not just partially completed but fully done and ready to be released to customers or stakeholders.
